I. Storm water Program Overview

Executive Summary This Storm Water Management Program (SWMP) was developed by the Village of Port Barrington

with the purpose of meeting the minimum standards required by the United States Environmental

Protection Agency (USEPA) under the National Pollutant Discharge Elimination System (NPDES)

Phase II program. Federal regulations through the USEPA require that all Municipal Separate

Storm Sewer Systems (MS4s), partially or fully in urbanized areas based on the 2000 census,

obtain storm water permits for their discharges into receiving waters.

The SWMP describes the procedures and practices that are implemented by the Village of Port

Barrington (Village) toward the goal of reducing the discharge of pollutants within storm water

runoff to comply with Federal standards. Compliance with the SWMP is intended to protect water

quality thus contributing to cleaner lakes and streams, improved recreational opportunities and

tourism, flood damage reduction, better aesthetics and wildlife habitat, and a safer and healthier

environment for the citizens.

Regulatory Background The NPDES permit process regulates the discharge of storm water from MS4s, construction sites,

and industrial activities based on amendments to the Clean Water Act in 1987 and the subsequent

1990 and 1999 regulations by the USEPA. In Illinois, the USEPA has delegated administration of

the federal NDPES program to the Illinois Environmental Protection Agency (IEPA). On December

20, 1999 the IEPA issued a General NPDES Phase II permit for all MS4s (ILR40 permit). Under the

General Permit, each MS4 was required to submit a Notice of Intent (NOI) declaring compliance

with the conditions of the permit by March 10, 2003. The original NOI described the proposed

activities and best management practices that occurred over the original 5-year period toward

the ultimate goal of developing a compliant SWMP. At the end of the 5th year (March 1, 2008)

the components of the SWMP were required to be implemented. The IEPA reissued the ILR40

permit on February 20, 2009 and again on February 10, 2016. A copy of the 2016 ILR40 permit is

included in Appendix A.

Any municipality covered by the ILR40 permit is also granted automatic coverage under the NPDES

General Permit ILR10 (ILR10 permit) for the discharge of storm water associated with construction

site activities for municipal construction projects disturbing one acre or more of land.

Municipalities are covered 30 days after the IEPA receives the project specific NOI from the

municipality. Private developments located within the Village are also required to obtain their

own project specific coverage under the ILR10 permit. A copy of the 2018 ILR10 permit is included

in Appendix B.

Water Quality Standards The IEPA is required under Sections 303(d), 305(b) and 314 of the Clean Water Act to assess waters

of the State (waters) and evaluate compliance with applicable water quality standards and

designated uses. Waters that are assessed as not achieving those standards are identified in the

Integrated Water Quality Report.

_____________________________________________________________________________________

2 | P a g e


Waters, such as lakes and streams, identified in the Integrated Water Quality Report in

accordance with Section 303(d) of the Clean Water Act are deemed impaired for specific chemical

constituents. Consequently, additional loadings (i.e. discharges) of those chemical constituents

may be restricted. In addition to possible restrictions on future loadings to listed waterbodies,

waters identified in accordance with Section 303(d) of the Clean Water Act are subject to the

development of Total Maximum Daily Loads (TMDLs).

Total Maximum Daily Load (TMDL) TMDL reports are created by IEPA for impaired waters. TMDL reports consist of data analysis to

quantitatively assess water quality, document waterbodies or segments of waterbodies that are

impaired, and identify potential contributing sources to the impairment. Based on those factors,

the amount and type of pollutant load reduction needed to bring water quality into compliance

is calculated. The TMDL report provides the scientific basis for states and local communities to

establish water quality-based controls to reduce pollutant loads from both point and non-point

sources. Information regarding TMDLs may be found at http://www.epa.state.il.us/water/tmdl/.

The Village reviews the status of TMDL reports as part of each year’s annual reports. Upon

issuance of additional TMDL requirements, the Village will create an implementation strategy that

will be described in the annual report and incorporated into the next revision of the SWMP.

Watersheds, Sub-Watersheds, and Receiving Waters Watersheds

A watershed is the area of land that drains (and contributes runoff) to a given stream or river.

Watersheds are important because pollution at the water’s source may impact water quality in

downstream areas. The Village of Port Barrington is located within the Upper Fox River watershed.

Figure 1 illustrates the location of the Village within the Upper Fox River watershed.

The Upper Fox Watershed, HUC 07120006, is located in the far northeastern part of Illinois and

the southeastern part of Wisconsin. The entire watershed covers 1,543 square miles of which the

Illinois portion covers 617 square miles or approximately forty (40) percent. The river enters

Illinois where it widens into a large area of interconnected lakes known as the Chain O'Lakes. Fox

Lake is the largest village in this area. From the chain, the river flows generally southward for 118

miles until it joins the Illinois River at Ottawa. Illinois towns and communities that are on the Fox

River include (from north to south): Fox Lake, Johnsburg, McHenry, Holiday Hills, Island Lake,

Burtons Bridge, Port Barrington, Cary, Fox River Grove, Algonquin, Carpentersville, West Dundee,

East Dundee, Elgin, South Elgin, St. Charles, Geneva, Batavia, North Aurora, Aurora, Montgomery,

Oswego, Yorkville, Plano, Millington, Sheridan and Ottawa. Collectively, the area surrounding the

Fox River is known as the Fox Valley. Around 1 million people live in this area.

Sub -Watersheds

A sub-watershed is the land area that contributes storm water to one of the receiving waters that

is tributary to a major river such as the Fox River. The Village is located within the Cary Creek-Fox

River and Cotton Creek sub-watersheds of the Fox River (see Figure 2).

Receiving Waters

A receiving water is a natural or man-made system into which storm water or treated wastewater

is discharged, including major rivers and their tributary stream systems. Receiving waters within

the Village include Slocum Lake Drain, Fiddle Creek and the Fox River (see Figure 3).

Status of Waters As can be seen on Figure 4, all three creeks/rivers within the Village are identified as “impaired”

by the IEPA. The most recent Integrated Water Quality Report and Section 303(d) Lists can be

found at http://www.epa.state.il.us/water/water-quality/index.html. At this time, no TMDLs

have been established for these waters.

TMDL statuses are reviewed annually and upon issuance of a TMDL requirement, an

implementation strategy or plan will be created and incorporated into the next SWMP revision. A

summary of the IEPA 2016 assessment is presented in Table 1.

Watershed Plans and Reports The following watershed plans and reports are applicable to the Village of Port Barrington.

9 Lakes Watershed-Based Plan (June 2014)

The Chicago Metropolitan Agency for Planning (CMAP) received a Clean Water Act grant from the

IEPA to develop a watershed plan for nine lakes in southwestern Lake County. While the plan was

originally undertaken to develop recommendations for purposes of achieving Total Maximum

Daily Loads (TMDL), the latter were never finalized by IEPA and their consultant as expected.

Thus, the purpose of the plan was to work with local stakeholders to develop recommendations

that upon implementation will help restore the water quality of local streams and the nine lakes

that are situated in three adjacent watersheds that drain to the Upper Fox River. The nine lakes

within the watershed planning area fail to meet all of their designated uses due to known causes

that are often related to land use. The 9 Lakes Watershed Planning Area lies within the Upper Fox

River Subbasin 3 and is situated primarily in southwest Lake County (92 percent) and partially in

McHenry County (eight percent). The 29.3 square mile area contains three primary watersheds:

Cotton-Mutton Creek (HUC – 0712000611xx; 10.2 sq. mi.), Slocum Lake Drain / Fiddle Creek (HUC

– 0712000611xx; 11.3 sq. mi.), and Tower Lake Drain (HUC – 0712000611xx; 5.9 sq. mi.).

Additionally, over six percent or 2.0 sq. mi. of the planning area is direct drainage to the Upper

Fox River Subbasin.

Upper Fox River/Flint Creek Watershed TMDL Final Stage 1 Report (March 2010)

The Stage 1 Total Maximum Daily Load (TMDL) report was presented as partial fulfillment by the

IEPA and USEPA in the development of TMDLs, as part of that state’s Clean Water Act (CWA)

Section 303(d) compliance. The purpose of the project was to develop TMDLs for 15 impaired

waterbodies in the Upper Fox River/Flint Creek watershed in Illinois.

The TMDL report provides the scientific basis for states and local communities to establish water

quality-based controls to reduce pollutant loads from both point (i.e., wasteload allocations) and

non-point sources (i.e., load allocations).

Illinois EPA uses a three-stage approach to develop TMDLs for a watershed:

Stage 1: Watershed characterization, historical dataset evaluation, data analysis,

methodology selection, data gap identification;

Stage 2: Data collection to fill in data gaps, if necessary; and

Stage 3: Model calibration, TMDL scenarios, and implementation plans.

The purpose of Stage 1 is to characterize the watershed background; verify impairments in the

listed waterbody by comparing observed data with water quality standards or appropriate

targets; evaluate spatial and temporal water quality variation; provide a preliminary assessment

of potential sources contributing to impairments; and describe potential TMDL development

approaches.

This report documents Stage 1 in the Illinois EPA approach for TMDL development. The report is

organized into seven main sections. Section 1.0 discusses the definition of TMDLs and targeted

impaired waterbodies in the Upper Fox River/Flint Creek watershed, for which TMDLs will be

developed. Section 2.0 describes the characteristics of the watershed, and Section 3.0 briefly

discusses the process of public participation and involvement. Section 4.0 describes the applicable

water quality standards and water quality assessment. Section 5.0 presents the assessment and

_____________________________________________________________________________________

9 | P a g e


analysis of available water quality data. Section 6.0 provides a description of each impaired

segment’s watershed and potential sources. Section 7.0 discusses the methodology selection for

the TMDL development, the data gaps, and provides recommendations for additional data

collection, if necessary.

Permit Coverage The ILR40 permit authorizes the discharge of storm water from MS4s into receiving waters. Storm

water is defined in the ILR40 permit as “storm water runoff, snow melt runoff, and surface runoff

and drainage”. MS4s include a conveyance or system of conveyances that are: owned by a state,

city, town, village, or other public entity that discharges storm water to waters of the U.S.;

designed or used to collect or convey storm water (e.g., storm drains, pipes, ditches); not a

combined sewer; and not part of a sewage treatment plant or publicly owned treatment works.

Regulated conveyance systems typically include roadway drainage systems, storm sewers, catch

basins, gutters, ditches, swales, manmade channels, and storm sewers.

The following discharges are authorized under the ILR40 permit, provided they have been

determined not to be substantial contributors of pollutants.

• Water line and fire hydrant flushing.

• Dechlorinated pH neutral swimming pool

discharges.

• Landscape irrigation water.

• Flows from riparian habitats and wetlands.

• Rising ground waters.

• Residual street wash water.

• Ground water infiltration.

• Discharges or flows from firefighting

activities.

• Pumped ground water.

• Routine external building wash down

which does not use detergents.

• Discharges from potable water sources.

• Dechlorinated water reservoir discharges.

• Foundation and drains.

• Pavement wash waters where spills or

leaks of toxic or hazardous materials have

not occurred.

• Air conditioning condensate.

• Storm sewer cleaning water.

• Irrigation water.

• Water from individual residential car

washing.

• Springs.

• Water from crawl space pumps.

The following discharges are NOT authorized by the ILR40 permit:

• Storm water discharges that are mixed with non-storm water or storm water associated with

industrial activity unless such discharges are in compliance with a separate NPDES permit.

• Discharges from dewatering activities (including discharges from dewatering of trenches and

excavations) are allowable if managed by appropriate controls as specified in a project's Storm

Water Pollution Prevention Plan, Soil Erosion and Sediment Control Plan, or Storm Water

Management Plan.

• Concrete and wastewater from washout of concrete (unless managed by an appropriate

control), drywall compound, wastewater from washout and cleanout of stucco, paint, form

release oils, curing compounds and other construction materials, fuels, oils, or other pollutants

used in vehicle and equipment operation and maintenance, soaps, solvents, or detergents,

_____________________________________________________________________________________

10 | P a g e


toxic or hazardous substances from a spill or other release, or any other pollutant that could

cause or tend to cause water pollution.

• Storm water discharges that the IEPA determines are not appropriately covered by the ILR40

permit.

MS4 Program Requirements Under the ILR40 permit, owners of regulated MS4 systems are required to develop, implement,

and enforce a Storm Water Management Program (SWMP) designed to reduce the discharge of

pollutants from their MS4 to the maximum extent practicable to protect water quality and satisfy

the appropriate water quality requirements of the Illinois Pollution Control Board Rules and

Regulations (35 III. Administrative Code, Subtitle C, Chapter 1) and the Clean Water Act.

“Maximum Extent Practicable” is a technology-based discharge standard established by Congress

in the Clean Water Act. Since no precise definition of “maximum extent practicable” exists, it

allows for maximum flexibility on the part of MS4s.

SWMPs must include six minimum control measures. For each of these six minimum measures,

MS4s must identify measurable goals and implement management practices to achieve those

measurable goals. The six minimum control measures include:

1. Public Education and Outreach on Storm Water Impacts

2. Public Involvement/Participation

3. Illicit Discharge Detection and Elimination

4. Construction Site Storm Water Runoff Control

5. Post-Construction Storm Water Management in New Development and Redevelopment

6. Pollution Prevention/Good Housekeeping for Municipal Operations

Detailed information regarding each of the six minimum control measures is provided in Section

IV of this document.

Storm Water Pollutants of Concern Polluted storm water runoff is commonly transported through MS4s, and then often discharged,

untreated, into local waterways. Storm water runoff naturally contains numerous constituents;

however, urbanization and urban activities (including municipal activities) typically increase

concentrations to levels that may impact water quality. The typical pollutants found in urban

storm water include sediment (from eroding streambanks and constructions sites), nutrients,

fecal coliform (from animals and failing septic systems), chlorides, oil and grease, pesticides,

herbicides, and metals. Table 3 identifies the pollutants of concern for the Village and their

potential sources. Table 4 identifies a list of municipal activities that have the potential for

generating pollutants. Additional information regarding pollutants of concern from residential,

commercial, and industrial properties is located in Appendix C. This SWMP describes the

procedures and practices that are implemented by the Village of Port Barrington toward the goal

of reducing the discharge of pollutants within storm water runoff in order to comply with the

ILR40 permit.

II. Program Management

Coordination The Village of Port Barrington has a Trustee-President form of government. The Board consists of

an elected President, six elected Trustees, and an elected Village Clerk. The Village administrator

has primary responsibility for managing the overall SWMP.

Storm Water Coordinator

The Village Administrator, or designee, is the Storm Water Coordinator for the Village and is

responsible for the oversight and implementation of this SWMP. The Storm Water Coordinator

has many different responsibilities, he/she:

• is the lead contact for coordination with the IEPA, SMC, Lake County, the development

community, and other external regulatory agencies;

• understands the requirements of the ILR40 permit, ensures that the SWMP meets the

requirements of the permit, and that the Village effectively implements the SWMP;

• ensures that the Village complies with all minimum Watershed Development Ordinance (WDO) provisions;

• is aware when a project is required to be authorized under the NPDES ILR10 General Permit

for Storm Water Discharges from Construction Site Activities (ILR10 permit). In these cases, the

Storm Water Coordinator should ensure that the Notice of Intent is received by IEPA at least

30 days prior to the start of construction;

• assists the development community in understanding when coverage under the ILR10 permit

is required, and whether construction sites comply with permit conditions; and

• understands the role illicit discharges play in the overall NPDES Phase II Program. In general,

an incidence of non-compliance must be filed with the IEPA for illicit discharges exiting an

MS4’s outfall into a receiving water. Additionally, if the illicit discharge is generated by a

construction site, it may be necessary for both the construction site permit applicant and the

Village to file the incidence of non-compliance form with the IEPA.

Coordination with the IEPA

The Village is required to complete annual reports which describe the status of compliance with

the ILR40 permit. The annual report must be posted on the Village’s website and submitted to the

IEPA by the first day of June each year. Each report covers the period from March of the previous

year through February of the current year. Records regarding the completion and progress of the

SWMP commitments must be kept by the Village and must be available for inspection by both the

IEPA and the general public. The annual report must contain the following information:

• An assessment of the appropriateness and effectiveness of the Village's identified BMPs and

progress towards achieving the statutory goal of reducing the discharge of pollutants to the

maximum extent practicable (MEP), and the Village's identified measurable goals for each of

the minimum control measures.

_____________________________________________________________________________________

13 | P a g e


• The status of compliance with permit conditions, including a description of each incidence of

non-compliance with the permit, and the Village’s plan for achieving compliance with a

timeline of actions taken or to be taken.

• Results of information collected and analyzed, including monitoring data, if any, during the

reporting period.

• A summary of the storm water activities the Village plans to undertake during the next

reporting cycle, including an implementation schedule.

• A change in any identified BMP or measurable goal that apply to the program elements.

• Notice that the Village is relying on another government entity to satisfy some of the permit

obligations (if applicable).

• An updated summary of any BMP or adaptive management strategy constructed or

implemented pursuant to any approved TMDL or alternate water quality management study.

Assess whether the WLA or other performance requirements for storm water discharges from

the Village are being met using the results of the monitoring program.

• If a Qualifying Local Program (QLP) is implementing any or all of the minimum control measures

on behalf of the Village.

Coordination with Lake County Storm Water Management Commission (SMC)

Coordination between the Village and SMC occurs through both participation in the SMC

sponsored Municipal Advisory Committee (MAC) forums and the WDO. SMC serves as a Qualifying

Location Program (QLP) by implementing various minimum control measures specified in the

ILR40 permit. Although SMC is not itself an MS4, it does perform activities related to each of the

six minimum control measures.

Coordination with Consultants

The Village may enlist the services of consultants to assist in the implementation of the SWMP

(including, but not limited to, plan review, site inspections, and enforcement), and the design of

Village projects.

Coordination of Contractors

The Village has a responsibility to hire contractors who are knowledgeable of the applicable

requirements of the ILR40 and ILR10 permits. The Village requires documentation that

appropriate training has been completed annually, for all contractors retained to manage or carry

out routine maintenance, repair, or replacement of public surfaces in current green infrastructure

or low impact design techniques applicable to such projects. Contractors may provide training to

their employees for projects which include green infrastructure or low impact design techniques.

Coordination with the Public

Coordination with the public occurs on several levels. In addition to the avenues described in this

SWMP, the public has the opportunity to comment on proposed preliminary and final plats

through the review process established by the Village’s Municipal Code.

_____________________________________________________________________________________

14 | P a g e


Coordination with the Development Community

The Village has a responsibility to assist the development community in understanding when an

ILR10 permit (for construction site storm water discharges) is required and whether construction

sites comply with permit conditions. A copy of the 2018 NPDES General Permit No. ILR10 is located

in Appendix B of this document.

Village staff should understand the role illicit discharges play in the overall NPDES Phase II

program. In general, an incidence of non-compliance (ION) must be filed with the IEPA for illicit

discharges exiting the Village’s outfall into a receiving water. Additionally, if the illicit discharge is

generated by a construction site, it may be necessary for both the applicant and the Village to file

the ION form with the IEPA. The Village has a responsibility to inform the development community

that they are required to hire contractors which meet the qualifications necessary under the

program.

III. Best Management Practices and Measurable Goals

Six Minimum Control Measures This SWMP includes six Minimum Control Measure (MCM) categories, each of which is necessary

in an effort to reduce/eliminate storm water pollution in receiving waters. The six required MCMs

are as follows:

1. Public Education and Outreach on Storm Water Impacts

2. Public Involvement/Participation

3. Illicit Discharge Detection and Elimination

4. Construction Site Storm Water Runoff Control

5. Post-Construction Storm Water Management in New Development and Redevelopment

6. Pollution Prevention/Good Housekeeping for Municipal Operations

Identification and Selection of Best Management Practices Effective storm water management is often achieved from a management systems approach as

opposed to an approach that focuses on individual practices. That is, the pollutant control

achievable from any given management system is viewed as the sum of the parts, taking into

account the range of effectiveness associated with each single practice, the costs of each practice,

and the resulting overall cost and effectiveness. Some individual practices may not be very

effective alone but in combination with others may provide a key function in highly effective

systems. The ILR40 permit encourages such system-building by stating the minimum

requirements in more general terms, which allows for the use of appropriate situation-specific

sets of practices (BMPs) that will achieve the MCMs.

To achieve a systematic approach for storm water management, the USEPA notes that these six

MCMs should be implemented by applying one or more BMPs appropriate to the location and

climate. The USEPA established a menu of BMPs that have been found to be representative of the

types of practices that can be applied successfully to achieve the six MCMs. The USEPA recognizes

that there is often site-specific regional and national variability in the selection of appropriate

BMPs as well as in the design constraints and pollution control effectiveness of practices. The list

of practices for each MCM is not all-inclusive and does not preclude the Village from using other

technically sound practices. However, the practice or set of practices chosen by the Village need

to achieve the MCM.

Measurable goals are BMP design objectives or goals that quantify the progress of program

implementation and the performance of the Village’s BMPs. They are objective markers or

milestones that the Village and the IEPA will use to track the progress and effectiveness of the

BMPs in reducing pollutants to the maximum extent practical. Measurable goals may be based on

one or more of the following general categories:

Tracking implementation over time: Where a BMP is continually implemented over the

permit term, a measurable goal can be developed to track how often or where this BMP is

implemented.

_____________________________________________________________________________________

16 | P a g e


Measuring progress in implementing the BMP: Some BMPs are developed over time and a

measurable goal can be used to track this progress until BMP implementation is completed.

Tracking total numbers of BMPs implemented: Measurable goals also can be used to track

BMP implementation numerically, e.g., the number of wet detention basins in place or the

number of people changing their behavior due to the receipt of educational materials.

Tracking program/BMP effectiveness: Measurable goals can be developed to evaluate BMP

effectiveness, for example, by evaluating a structural BMP’s effectiveness at reducing

pollutant loadings or evaluating a public education campaign’s effectiveness at reaching and

informing the target audience to determine whether it reduces pollutants to the maximum

extent practical. A measurable goal can also be a BMP design objective or a performance

standard.

Tracking environmental improvement: The ultimate goal of the NPDES storm water program

is environmental improvement, which can be a measurable goal. Achievement of

environmental improvement can be assessed and documented by ascertaining whether state

water quality standards are being met for the receiving waterbody or by tracking trends or

improvements in water quality (chemical, physical, and biological) and other indicators such

as the hydrologic or habitat condition of the waterbody or watershed.

IV. Storm water Management Program

This section outlines the six required MCMs and description of the BMPs that are implemented, including

measurable goals and the method of tracking.

MCM #1: Public Education and Outreach The Village of Port Barrington utilizes a variety of methods to educate and provide outreach to

the public about the impacts of storm water discharges on waterbodies and the steps that the

public can take to reduce pollutants in storm water runoff. Outreach publications includes Village

contact information to encourage residences to report environmental concerns.

Distribution of Educational Materials

Educational materials are distributed in the Village newsletter, on the Village website, at take-a-

way racks in Village offices, at outreach events, and at scheduled meetings with the general public.

Topics include:

• Storm water BMPs including cost-benefits and implementation guidance.

• Construction site activities (soil erosion and sediment control BMPs).

• Effective pollution prevention measures regarding storage and disposal of fuels, oils, and

newsletter.

Household Hazardous Waste Program

The average garage contains a lot of products that are classified as hazardous wastes, including

paints, stains, solvents, used motor oil, pesticides, and cleaning products. While some household

hazardous waste may be dumped into storm drains, most enters the storm drain system as a

result of outdoor rinsing and cleanup. Improper disposal of household hazardous waste can result

in acute toxicity to downstream aquatic life. The desired neighborhood behavior is to participate

in household hazardous waste collection days, and to use appropriate pollution prevention

techniques when conducting rinsing, cleaning, and fueling operations.

For household products that cannot go into the curbside recycling program or in landfills, there

are several ways to dispose of these materials through programs organized by the Village and

Prairieland Disposal & Recycling. As a member, Port Barrington residents are provided with a

variety of waste management services, programs, and resource materials that include collections

for special materials that are not allowed as part of curbside recycling or should not go into the

garbage due to toxicity or recoverability (reuse and recycling).

Measurable Goals

1. Support and publicize SWALCO and Prairieland Disposal & Recycling efforts.

Tracking

1. Track the number of household hazardous waste disposal events that occur within the Village

that are coordinated with SWALCO or Prairieland Disposal & Recycling.

2. Confirm link to SWALCO and Prairieland Disposal & Recycling website on the Village’s website.

Residential Recycling

Recycling is an effective means of achieving pollution prevention goals. Recycling is a series of

activities that includes collecting recyclable materials that would otherwise be considered waste,

sorting, and processing recyclables into raw materials such as fibers, and manufacturing raw

_____________________________________________________________________________________

19 | P a g e


materials into new products. Trash and floating debris in waterways can become significant

pollutants and potentially pose a threat to wildlife and human health (e.g., choking hazards to

wildlife and bacteria to humans). For residents, the most convenient kind of collection is curbside

collection. The Village offers weekly curbside refuse collection for its residents. Prairieland

Disposal & Recycling provides every single-family home with a 96-gallon container for both

garbage and recycling. The recyclables accepted include newspaper, mixed paper, corrugated

cardboard, and mixed recyclables such as glass bottles and jars, steel/tin/bi-metal cans, aluminum

cans/foils/tins and various plastic containers.

Measurable Goals

1. Continue to offer and promote curbside waste and recycling collection for residents.

MCM #2: Public Participation and Involvement The public participation and involvement program allows input from citizens during the

development and implementation of the SWMP.

Public Review

The Village conducts one public meeting annually to present the annual report to the Village

Board during an open meeting. This public meeting allows the public to provide input as to the

adequacy of the Village's MS4 Program. Comments are evaluated for inclusion and incorporated

into the next revision of the SWMP as appropriate. The meeting is typically part of a regular Village

Board meeting. Public notification about the meeting content complies with Illinois’ public notice

requirements.

Measurable Goals

Environmental Justice Areas

Environmental justice is the fair treatment and meaningful involvement of all people regardless

of race, color, national origin, or income, with respect to the development, implementation, and

enforcement of environmental laws, regulations, and policies. The EPA has this goal for all

communities and persons across the nation. It will be achieved when everyone enjoys the same

_____________________________________________________________________________________

20 | P a g e


degree of protection from environmental and health hazards, and equal access to the decision-

making process to have a healthy environment in which to live, learn, and work.

“Potential” environmental justice communities have been identified based on IEPA guidance to

include communities with a low-income and/or minority population greater than twice the

statewide average. In addition, a community may be considered a potential environmental justice

community if the low-income and/or minority population is less than twice the state-wide average

but greater than the statewide average and that has identified itself as an environmental justice

community. If the low-income and/or minority population percentage is equal to or less than the

statewide average, the community should not be considered a potential environmental justice

community. The following web application is another resource that can be used to determine if

an area would qualify for consideration as an environmental justice community

https://ejscreen.epa.gov/mapper/index.html. Using the EPA environmental justice website, the

Demographic Index was reviewed. The Demographic Index is an index based on the average of

two demographic indicators; percent low-income and percent minority, defined below.

• Percent Minority: The percent of individuals in a block group who list their racial status

as a race other than white alone and/or list their ethnicity as Hispanic or Latino.

• Percent Low-Income: The percent of a block group's population in households where the

household income is less than or equal to twice the federal "poverty level."

Using the EPA environmental justice website, the Village determined that there are no areas

within the Village that exceed the 70th percentile for the state.

Measurable Goals

1. Repeat the process of determining environmental justice areas annually. If any environmental

justice areas are identified within the community, ensure that BMP efforts are targeted at

these areas.

Tracking

1. Provide results of the environmental justice screening effort in the Annual Report.

2. If applicable, track efforts to address EJ areas.

Tracking

1. Track the subject matter and number of meetings attended by Village staff.

MCM #3: Illicit Discharge, Detection, and Elimination An “illicit discharge” is defined in 40 CFR 122.26(B)(2) as any discharge to a MS4 that is not

composed entirely of storm water, except discharges pursuant to a NPDES permit (other than the

NPDES permit for discharges from the municipal separate storm sewer) and discharges resulting

from firefighting activities. Currently, illicit discharges contribute considerable pollutant loads to

receiving waters. Illicit discharges can enter the storm sewer system as either an indirect

connection (e.g., spills that enter the storm drain system at an inlet and dumping a liquid into a

storm drain inlet) or direct piping connections to the storm sewer system.

Understanding the potential locations and the nature of illicit discharges in urban watershed is

essential to find, fix, and prevent them. The Village has identified “outfalls” for the purpose of

implementing this SWMP. An “outfall” is defined in 40 CFR 122.2 as a point source where a

municipal separate storm sewer discharges to a waters of the U.S. For the purposes of this SWMP,

an outfall is a storm sewer outlet, or other open conveyance point discharge location, that

discharges into a Waters of the U.S, receiving stream, or another MS4.

Storm Sewer System Map

As required by the NPDES ILR40 permit, the Village developed a map of the municipal storm sewer

system identifying the location of all outfalls, and the names and location of all receiving waters.

The storm sewer system map is meant to demonstrate a basic awareness of the intake and

_____________________________________________________________________________________

22 | P a g e


discharge areas of the system. It is needed to help determine the extent of discharged dry weather

flows, the possible sources of the dry weather flows, and the particular water bodies these flows

may be affecting. The outfall map is revised as needed to incorporate permitted outfalls

associated with new developments.

Measurable Goals

1. Maintain the Village’s storm sewer system map.

Tracking

1. Track updates to the storm sewer map, including modification dates and changes made to

outfalls.

Regulatory Authority

The ILR40 permit requires the Village to institute an ordinance that prohibits non-storm water

discharges into their MS4 to the extent allowable under current State, Tribal, and local law. To

limit illicit discharges, the ordinance must prohibit both illicit connections as well as the illegal

discharge of pollutants into the storm sewer drainage system.

Effective implementation of an Illicit Discharge Detection and Elimination (IDDE) program requires

adequate legal authority to remove illicit discharges and prohibit future illicit discharges. This

regulatory authority is achieved through the Village’s Municipal Code (Chapter 50: Storm Water

Discharges and Chapter 54: Groundwater Protection Regulations) which contains restrictions on

illicit discharges and storm water management. The objectives of the Village’s Illicit Discharge

Ordinance are:

• To regulate the contribution of pollutants to the MS4 by storm water dischargers by any

user;

• To prohibit illicit connections and discharges to the MS4; and

• To establish legal authority to carry out all inspection, surveillance, monitoring, and

enforcement procedures necessary to ensure compliance with the Village’s Illicit

Discharge Ordinance.

Additionally, the IEPA has regulatory authority to control pollutant discharges and can take the

necessary steps to correct or remove an inappropriate discharge over and above the Village’s

jurisdiction.

_____________________________________________________________________________________

Measurable Goals

1. Enforce the Village’s Municipal Code, specifically the Village’s Illicit Discharge Ordinance

(Chapter 50) and the Groundwater Protection Regulations (Chapter 54).

Tracking

1. Track the number of enforcement actions related to illicit discharges and groundwater

impacts.

Lake County Watershed Development Ordinance

Several provisions of the Lake County Watershed Development Ordinance (WDO) prohibit illicit

discharges as part of the development process. Regulated developments are also required to

meet the soil erosion and sediment control (SESC) standards of the WDO. Furthermore, the WDO

prohibits illicit discharges into the storm water management system generated during the

development process.

Measurable Goals

1. Adhere to the requirements of the WDO.

Tracking

1. Track the number of violations.

Visual Dry Weather Inspection Program

Inspecting storm water outfalls during dry-weather conditions reveals whether non-storm water

flows exist. If non-storm water flows are observed, they can be screened and tested to determine

whether pollutants are present. Dry weather discharges are typically composed of sewage from

pipes or septic systems; washwater from various residential, commercial, and industrial activities

and operations; liquid wastes such as oil, paint, and process water; tap water from leaks occurring

in the water supply system; landscape irrigation; and groundwater. Water quality testing is used

to conclusively identify flow types found during dry weather inspections. Testing can distinguish

illicit flow types (e.g., sewage, liquid wastes, commercial/industrial washwater) from cleaner

discharges (e.g., tap water, landscape irrigation, and groundwater).

The Village’s procedure for the identification of illicit discharges is included in Appendix D. Step-

by-step instructions for identifying storm sewers suspected of containing pollutants, suggestions

for actions to be taken to determine the sources of identified pollutants, and steps for correcting

identified problems are provided. The results of these procedures are intended to serve as

indicators of pollution, rather than to provide specific quantitative analysis. If the presence of

pollutants is indicated, the detective work of identifying the source of the discharge can begin.

Once the source is identified, it can then be corrected.

_____________________________________________________________________________________

24 | P a g e


Measurable Goals

1. Conduct outfall inspections annually (5-year rotation) during periods of dry weather.

2. Follow up on any observations of dry weather flow.

Tracking

1. Track the number of outfalls inspected annually.

2. Track the number and location of illicit discharges/connections found.

3. Track the number and location of illicit discharges repaired/replaced.

High Priority Areas

The ILR40 permit does not cover storm water discharges mixed with non-storm water, or storm

water associated with industrial activities. However, industrial and commercial businesses can

potentially contribute varying types and amounts of pollutants to the Village’s MS4 through poor

housekeeping practices. The Village of Port Barrington has developed an Industrial and

Commercial Inspection (ICI) Program designed to identify and manage pollutants entering the

Village’s storm sewer from sources associated with industrial and commercial properties. Key

elements of the ICI Program include a facility inventory, source identification, public outreach and

education, inspections and enforcement.

Measurable Goals

1. Maintain a database of industrial and commercial businesses that have a high potential for

contributing to water pollution.

2. Inspect facilities annually.

3. Notify the IEPA of NPDES ILR00 Permit infractions and recommend enforcement actions,

where appropriate.

MCM #4: Construction Site Runoff Control By many accounts, the most environmentally dangerous period of development is the initial

construction phase, when land is cleared of vegetation and graded to create a proper surface for

construction. The removal of natural vegetation and topsoil makes the exposed area particularly

susceptible to erosion, causing transformation of existing drainage areas and disturbance of

sensitive areas.

The ILR40 permit requires the Village to develop, implement, and enforce a program to reduce

pollutants in any storm water runoff to its MS4 from construction activities that result in a land

disturbance of greater than or equal to one acre. Reduction of storm water discharges from

construction activity disturbing less than one acre must be included in the program as well if that

construction activity is part of a larger common plan of development or sale that would disturb

one acre or more. Development in the Village is subject to the provisions of the WDO.

Lake County Watershed Development Ordinance (WDO)

The goal of the WDO is to ensure that new development does not increase existing storm water

problems or create new ones. The WDO establishes standards for runoff maintenance, detention

sites, soil erosion and sediment control, water quality, wetlands, and floodplains. The WDO is the

regulatory mechanism that requires the use of soil erosion and sediment controls on development

sites. The soil erosion and sediment control provisions are included in Article 6 of the WDO. At a

minimum, these standards apply to any development project that hydrologically disturbs 5,000

square feet of land or more. In addition, the WDO requires applicants that hydrologically disturb

greater than 1-acre to seek coverage under the NPDES Construction Site General Permit ILR10 by

filing a Notice of Intent (NOI) with IEPA. The Village of Port Barrington has adopted the Lake

County WDO and is currently a Certified Community for the review, permitting, inspection, and

enforcement of the provisions of the WDO.

_____________________________________________________________________________________

26 | P a g e


Measurable Goals

1. Review site plans and issue permits in accordance with the WDO.

Tracking

1. Track development projects from the initial submittal to issuance of the Watershed

Development Permit.

2. Track projects that require an NPDES Construction Site General Permit ILR10.

Construction Site Inspections & Enforcement Procedures

Article 5 of the WDO contains both recommended and minimum requirements for the inspection

of development sites. As a Certified Community, the Village of Port Barrington is responsible for

conducting these inspections. For major developments, site inspections occur, at a minimum,

upon completion of installation of soil erosion and sediment controls, prior to the start of any

other land disturbing activities, after final stabilization and landscaping, and prior to the removal

of soil erosion and sediment controls.

Article 12 of the WDO specifies the legal actions that may be taken and the penalties that may be

imposed if the provisions of the WDO are violated. If development activities on a development

site are not in compliance with the requirements of the WDO, the Village may issue a stop work

order on all development activity on the development site or on the development activities that

are in direct violation of the WDO. In addition, failure to comply with any of the requirements of

the WDO constitutes a violation of the WDO, and any person convicted of violating the WDO may

be fined.

Measurable Goals

1. Document and track site inspections on development sites.

Tracking

1. Maintain inspection reports for each development project.

2. Track the number of construction site violations related to soil erosion and sediment control.

MCM #5: Post Construction Storm Water Management in New Development and

Redevelopment The management of storm water runoff from sites after the construction phase is vital to

controlling the impacts of development on urban water quality. The increase in impervious

surfaces such as rooftops, roads, parking lots, and sidewalks due to land development can have a

detrimental effect on aquatic systems. Heightened levels of impervious cover have been

associated with stream warming and loss of aquatic biodiversity in urban areas. Runoff from

impervious areas can also contain a variety of pollutants that are detrimental to water quality,

including sediment, nutrients, road salts, heavy metals, pathogenic bacteria, and petroleum

hydrocarbons.

_____________________________________________________________________________________

27 | P a g e


Regulatory Program

The WDO established the minimum storm water management requirements for development,

including requirements for post- construction runoff control. The WDO requires all applicants to

adopt storm water management strategies for controlling post-construction storm water runoff

on development sites. All development must adopt storm water management strategies that

minimize increases in storm water runoff rates, volumes, and pollutant loads from development

sites. Proposed storm water management strategies must address the runoff volume reduction

requirements and include appropriate storm water BMPs to address the other applicable post-

construction runoff control requirements of the WDO. Applicants are also required to adopt

strategies that incorporate storm water infiltration, reuse, and evapotranspiration of storm water

into the project to the maximum extent practicable. Types of techniques include green roofs, rain

gardens, rain barrels, bio-swales, permeable piping, dry wells, and permeable pavement.

The WDO requires that maintenance plans be developed for all storm water management systems

designed to serve major developments. Such maintenance plans must include the following:

• Description of all maintenance tasks.

• Identification of the party or parties responsible for performing such maintenance tasks.

• Description of all permanent maintenance easements or access agreements, overland flow

paths, and compensatory storage areas.

• Description of dedicated sources of funding for the required maintenance.

The WDO also requires that all storm water management systems be located within a deed or

plat restriction to ensure that the system remains in place in perpetuity and that access to the

system is maintained in perpetuity for inspection and maintenance purposes.

Measurable Goals

1. Document BMPs approved on development sites.

2. Ensure maintenance plans are prepared for all storm water management systems as required

by the WDO.

Tracking

1. Track projects with maintenance plans.

Storm Water Management Facility Inspections

Regular inspection is essential to maintain the effectiveness of post-construction storm water

management facilities. Inspection and maintenance of facilities can be categorized into two

groups: (1) expected routine maintenance, and (2) non-routine maintenance (i.e., repairs).

Routine maintenance refers to checks performed on a regular basis to keep the facility in good

working order and aesthetically pleasing. In addition, routine inspection and maintenance is an

efficient way to reduce the chance of polluting storm water runoff by finding and correcting

problems before the next rain. The failure of structural storm water facilities can lead to

downstream flooding, causing property damage, injury, and even death.

_____________________________________________________________________________________

28 | P a g e


The Village attempts to inspect approximately 20% of all public and private storm water

management facilities a year; resulting in a 5-year inspection interval. Observed erosion,

seeding/reseeding needs, and slope stabilization needs are documented. During the inspections,

staff identify facilities that would most benefit from a retrofit or other enhancements. SMC’s

Streambank/Shoreline Stabilization Manual is used as a starting point in choosing the appropriate

BMP for remediation activities. Impacts and effects due to climate change are taken into

considered when making recommendations. A master list of storm water management facilities

is maintained and updated on a regular basis.

Measurable Goals

1. Inspect 20% of all public and private storm water management facilities on an annual basis.

Recommend remedial actions as appropriate.

2. Evaluate the feasibility of retrofits and enhancements to storm water management facilities.

Tracking

1. Track storm water management facility inspection and maintenance data.

2. Track retrofits/enhancements that occur within the permit period.

MCM #6: Pollution Prevention / Good Housekeeping for Municipal Operations The Village is responsible for the care and upkeep of Village-owned property, municipal roads,

and maintenance yards. Many maintenance activities are performed by Village staff; however,

contractors are employed to perform specific activities. The Village maintains compliance with

permit requirements by incorporating pollution prevention and good housekeeping storm water

quality management into day-to-day operations. On-going education and training is provided to

staff to ensure they have the knowledge and skills necessary to perform their functions effectively

and efficiently. The Village of Port Barrington implements the following pollution prevention and

good housekeeping programs.

Catch Basin/Inlet Cleaning

Catch basins are chambers or sumps that allow surface water runoff to enter the storm water

drainage system. Many catch basins are below the invert of the outlet pipe and are intended to

retain coarse sediment. By trapping sediment, the catch basin prevents solids from clogging the

storm sewer and being washed into receiving waters. Catch basins must be cleaned periodically

to maintain their ability to trap sediment. The removal of sediment, decaying debris, and highly

polluted water from catch basins has aesthetic and water quality benefits, including reducing foul

odors, reducing suspended solids, and reducing the load of oxygen-demanding substances that

reach receiving waters. Catch basins are cleaned manually or by specially designed equipment.

Before any materials can be disposed, it may be necessary to perform a detailed analysis to

characterize the waste. However, material removed from catch basins is usually stored at the

Village’s maintenance yard and disposed in a conventional landfill.

The Village inspects all catch basins annually and cleans catch basins and inlets on an as needed

basis (e.g., complaints, standing water, etc.). Catch basins found to have structural deficiencies

_____________________________________________________________________________________

29 | P a g e


are reported to the Village Administrator. Necessary remedial actions are completed by a

contractor or incorporated into a capital project.

Tracking

1. Track the amount of pesticides and fertilizers used by location.

2. Maintain a list of contractors that meet the ILR40 training requirements.

Snow Removal and Ice Control

The Village of Port Barrington handles snow and ice removal on Village Roadways. During snow

removal and ice control activities, salt, de-icing chemicals, abrasives, and snow melt may pollute

storm water runoff. To address these potential pollutants, the following procedures for the

“winter season” (November 1 through May 1) are implemented.

Roadway Ice Control - Use the minimal amount of salt, de-icing chemicals, and additives necessary

for effective control. Prior to November 1, preparation work to obtain seasonal readiness is

completed. These tasks include installing, inspecting, re-conditioning, testing, and calibrating of

spreaders and spinners per the National Salt Institution Application Guidelines. Driver training is

also conducted annually for all drivers. The completion of these preparatory tasks helps to ensure

that only the necessary level of salt is applied.

Snow Plowing - Snow plowing activities direct snow off the pavement and onto the parkways. This

reduces the amount of salt, chemical additives, abrasives, or other pollutants that go directly into

the storm sewer system.

Participation in Watershed Group – Village staff participate in a watershed group(s) organized to

implement control measures which will reduce the chloride concentration in receiving streams in

the watershed.

Salt Delivery and Storage - Steps are taken to ensure that the delivery, storage, and distribution

of salt does not pollute storm water runoff. The floor of the enclosed salt storage building, and

adjacent receiving/unloading area is constructed of impervious material. The limits of the salt

piles are pushed back away from the door opening to minimize potential illicit runoff.

Brine Tanks – Steps are taken to ensure that the delivery, storage and distribution of brine does

not pollution storm water runoff.

_____________________________________________________________________________________

31 | P a g e


Measurable Goals

1. Continue to implement the pre-season procedures related to roadway ice control, snow

plowing, participation in watershed groups, driver training, and management of salt/brine

delivery and storage.

Tracking

1. Track the amount of de-icing chemicals and salt used.

2. Maintain list of staff that have completed the pre-season training.

3. Track participation in watershed groups by date, topic, and location.

Vehicle and Equipment Maintenance

Vehicle and equipment maintenance procedures and practices are designed to minimize or

eliminate the discharge of pollutants to the storm water management system, including receiving

waters. The following standard procedures are implemented.

Waste Oil - Used motor oil, transmission fluids, gear lubes, brake fluids and other vehicle fluids

(except antifreeze) are collected and stored in approved containers. The waste oil tank is emptied

by a private company and removed for recycling.

Antifreeze - Used antifreeze is stored in a 120-gallon double walled tank. It is emptied by a private

company and removed for recycling.

Batteries - Used batteries are stored in the vehicle maintenance area and are and removed for

recycling weekly by a private battery supplier.

Tires - Used tires are picked up and recycled by a local vendor as accumulated. Tires are stored

outside at the Village’s garage until picked up for disposal.

Other - Private certified companies perform all air-conditioning related work; therefore, the

disposal of Freon is not handled directly by the Village. Cleaning fluids and solvents are contained

within an enclosed tank and maintained by a private licensed special waste company.

Measurable Goals

1. Continue to implement the procedures for vehicle and equipment maintenance.

Tracking

1. Track the amount of materials removed by a private contractor.

Waste Management

Waste Management consists of implementing procedural and structural practices for handling,

storing, and disposing of wastes generated by Village maintenance activity. This helps prevent the

release of waste materials into receiving waters. Waste management practices include removal

of materials such as asphalt and concrete maintenance by-products, excess earth excavation,

_____________________________________________________________________________________

32 | P a g e


contaminated soil, hazardous wastes, sanitary waste, and material from within triple basins. The

following standard procedures are implemented.

Spoil Stock Pile - Asphalt and concrete maintenance by-products and excess earth excavation

materials are temporarily stored in the stock pile in the maintenance yard. Attempts are made to

recycle asphalt and concrete products prior to storage in the spoil stock pile. Licensed waste

haulers are contracted to remove and dispose of the contents at a licensed landfill. Surface runoff

from this area is largely contained.

Contaminated Soil Management - Contaminated soil/sediment generated during an emergency

response or identified during construction activities is collected and management for treatment

or disposal. Attempts are made to avoid stockpiling of the contaminated soil.

Hazardous Waste - All hazardous wastes area stored in sealed containers constructed of

compatible material and labeled. The containers are located in non-flammable storage cabinets

or on a containment pallet. These items include paint, aerosol cans, gasoline, solvents, and other

hazardous wastes. Care is taken to avoid overfilling containers. Paint brushes and equipment used

for water and oil-based paints are cleaned within the designated cleaning area. The Department

of Public Works maintains oversight of hazardous waste generated by the Village. Containerized

hazardous waste materials are disposed of or recycled through a contract arrangement with a

third party hazardous waste disposal firm.

Measurable Goals

1. Properly handle, store, and dispose of wastes generated by Village maintenance activities.

Tracking

1. Track the removal of wastes from the maintenance facility.

Spill Response Plan

Spill prevention and control procedures are implemented wherever non-hazardous chemicals

and/or hazardous substances are stored or used. These procedures and practices are

implemented to prevent and control spills in a manner that minimizes or prevents discharge to

the storm water drainage system and receiving waters.

The following general guidelines are implemented to prevent spills:

• Ensure all hazardous substances are properly labeled.

• Store all hazardous wastes in sealed containers constructed of compatible material and

labeled.

• Locate items, such as paint, aerosol cans, gasoline, solvents and other hazardous wastes, in

non-flammable storage cabinets or on a containment pallet.

• Do not overfill containers.

• Provide secondary containers when storing hazardous substances in bulk quantities (greater

than 55 gallons).

_____________________________________________________________________________________

33 | P a g e


• Dispense and/or use hazardous substances in a way that prevents release.

Non-Hazardous Spills/Dumping - Non-hazardous spills typically consist of an illicit discharge of

household material(s) into the street or storm water management system. Upon notification or

observance of a non-hazardous illicit discharge, the Public Works Department or Police

Department implement the following procedure:

• Sand bag the receiving inlet to prevent additional discharge into the storm sewer system.

• Check structures (immediate and downstream) and if possible, vacuum materials out. Jet

structure to dilute and flush the remaining unrecoverable illicit discharge.

• Clean up may consist of applying “Oil Dry” or sand and then sweeping up the remnant

material.

• On-site personnel document the location, type of spill, and action taken.

Hazardous Spills - Upon notification or observance of a hazardous illicit discharge, the Public

Works Department or Police Department implement the following procedure:

• Call 911, explain the incident. The Fire Department responds.

• Village Police provide emergency traffic control, as necessary.

• The Fire Department evaluates the situation and applies “No Flash” or “Oil Dry” as necessary.

• The Fire Department’s existing emergency response procedure for hazardous spill

containment clean-up activities is followed.

• On-site personnel document the location, type of spill, and action taken.

Measurable Goals

1. Implement the Spill Response Plan outlined above.

Tracking

1. Track the location, type, and action taken for spill events and any related illicit discharges.

V. Employee Training The Village has developed an in-house employee training program designed to educate staff

about the SWMP. The end goal of the training program is to provide training that results in the

prevention and reduction of pollutant discharge to the maximum extent practicable. The program

is repeated annually both to train new employees and to keep its objectives fresh in the minds of

more senior employees. The training program is also flexible and will be adapted as the storm

water management needs change over time. Contractors are responsible for providing proof of

similar training. Key topics include the following:

• Preventing and reducing storm water pollution from activities such as new construction and

land disturbances; park and open space maintenance; fleet and building maintenance;

operation of storage yards; snow disposal; and de-icing material storage, handling, and use

on roadways.

• Storm water system maintenance procedures for proper disposal of street cleaning debris

and catch basin material.

• Impacts of flood management projects on water quality.

• Non-point source pollution control.

• Green infrastructure controls.

• Aquatic habitat.

• Best Management Practices (BMPs).

• Potential sources of contaminants.

• Pollution prevention work practices.

• How to prevent and reduce the discharge of pollutants to the maximum extent practicable.

• Hazards associated with illegal discharges and improper disposal of waste and the

requirements and mechanisms for reporting such discharges.

Additional annual training is required for Village employees who manage or are directly involved

in (or who retain others who manage or are directly involved in) the routine maintenance, repair,

or replacement of public surfaces. Training is focused on current green infrastructure/low impact

design techniques applicable to projects involving the routine maintenance, repair, or

replacement of public surfaces.

VI. Monitoring, Recordkeeping, and Reporting The SWMP represents an organized approach to achieving compliance with the NPDES Phase II

program for both public and private activities within the Village. Land development,

redevelopment, and transportation improvement projects were required to comply with the

provisions of the Village’s Municipal Code prior to acceptance of the SWMP. Additionally, the

Village had numerous written and unwritten procedures for various tasks. This SWMP documents

and organizes previously existing procedures and incorporates new ideas to create one cohesive

program that addresses pre-development, construction, post-development, and municipal

activities.

The following sections describe how the Village will monitor and evaluate the SWMP based on

the above stated objective.

Monitoring and Assessment Program The Village conducts water quality monitoring in accordance with Section V.A.2.b of the ILR40

permit. Monitoring includes water quality testing of receiving waters upstream and downstream

of the Village, within designated streams.

Grab samples at these locations are collected within 48 hours of a precipitation event greater than

or equal to one quarter inch in a 24-hour period. The water quality analysis includes the following

parameters: total suspended solids, total nitrogen, total phosphorous, fecal coliform, chlorides,

and oil and grease. Water quality data is summarized and reviewed annually to detect changes

between upstream and downstream sampling locations.

Recordkeeping The Village retains records for five years after the expiration of the ILR40 permit (current permit expires on February 28, 2021). Records include the Village’s NOI, SWMP, annual reports, and monitoring data. Records are kept on-site (or locally available) and are accessible to the IEPA for review at the time of an on-site inspection. These records are available to the public during regular business hours. Advance notice is required.

The Village’s NOI, SWMP, and annual reports are posted on the Village’s website. Annual Reports are maintained on the Village’s website for 5 years.

Reporting The Village is required to submit an annual report to the IEPA by the first day of June for each year

that the ILR40 permit is in effect. Each annual report covers the period from March of the previous

year through March of the current year. The annual report includes the following:

• An assessment of the appropriateness and effectiveness of the Village’s identified BMPs and

progress towards achieving the statutory goal of reducing the discharge of pollutants to the

maximum extent practicable (MEP), and the Village’s identified measurable goals for each of

the minimum control measures.

• The status of compliance with permit conditions, including a description of each incidence of

non-compliance with the permit, and the Village’s plan for achieving compliance with a

timeline of actions taken or to be taken.

• Results of information collected and analyzed, including monitoring data, if any, during the

reporting period.

• A summary of the storm water activities the Village plans to undertake during the next

reporting cycle, including an implementation schedule.

• A change in any identified BMPs or measurable goals that apply to the program elements.

• Notice that the Village is relying on another government entity to satisfy some of the permit

obligations (if applicable).

• An updated summary of any BMP or adaptive management strategy constructed or

implemented pursuant to any approved TMDL or alternate water quality management study.

Using the results of the monitoring program, assess whether the waste load allocation (WLA)

or other performance requirements for storm water discharges from the MS4 are being met

(if applicable).

VII. Program Evaluation In conjunction with the preparation of the annual report, BMPs implemented by the Village are

evaluated annually to determine the effectiveness of the SWMP. Areas of program effectiveness, as

well as areas which do not appear to be improving, are identified and described in the annual report.

This information is used to provide insight into how the program may need to evolve. The following

are some indicators that the BMPs are appropriate:

• A reduced number of outfalls having positive indicators for potential pollutants.

• An improvement, or no change, in the annual monitoring results.

• Increased stakeholder involvement.

• Reduced number of violations.

• Improved storm water management facility quality (including conversion of dry bottom or turf

basins to naturalized basins; removal of excess sediment accumulation and a general increase in

maintenance activity on facilities throughout the Village).

• Reduced use of chloride.

• Improved awareness of water quality and other NPDES program aspects by both Village staff and

contractors.

Monitoring Program Evaluation The results of the water quality monitoring program are used to further gage the effects of the SWMP

on the physical/habitat-related aspects of receiving waters and the effectiveness of BMPs. Possible

causes of documented degradation are investigated, and appropriate corrective actions incorporated

into future versions of the SWMP. A discussion of water quality monitoring efforts is described in each

annual report.

Illicit Discharge Detection & Elimination Program Evaluation There is typically a lower chance of observing polluted dry-weather flows in residential and newer

development areas, while older and industrial land use areas have a higher incidence of observed dry-

weather flows. The Village reviews the results of the dry weather outfall program annually to examine

whether any trends can be identified that relate to the age or land use of a developed area. If so,

these conclusions may guide future outfall inspection activities.

Indirect or subtle discharges such as flash dumping are difficult to trace to their sources and can only

be remedied through public education and reporting. Therefore, it is expected that to some degree

they will continue, although at a reduced magnitude and frequency. Although the outfall inspection

program will be successful in identifying and eliminating most pollutants in dry-weather discharges,

the continued existence of dry-weather flows requires an ongoing commitment to continue the outfall

screening program.

It is logical to assume that completion of the initial dry-weather efforts eliminated the majority of the

dry-weather pollution sources. However, new sources may appear in the future as a result of mistaken

cross connections from redevelopment, new-development, or remodeling. Annual dry-weather

outfall inspections will determine the effectiveness of the program on a long-term basis and show

ongoing improvement through a reduced number of outfalls having positive indicators of potential

pollutants. A description of the outfall inspection program and an analysis of the results are included

in the annual report.

SWMP Evaluation The following types of questions/answers are discussed internally each year. Suggested

improvements are noted and incorporated into a revised SWMP document. The SWMP is revised

approximately every five years.

• Are proper storm water management practices integrated into planning, designing, and

construction of both public and private projects?

• Are efforts to incorporate storm water practices into maintenance activities effective and

efficient?

• Is the training program sufficient?

• Is the SWMP sufficient with respect to both the BMPs and measurable goals described for each

of the six Minimum Control Measures?

• Are the procedures for implementing the SWMP adequate?

• Are there any TMDL Reports within the community and if yes, is there an action plan for

compliance?

• Were there any issues of non-compliance and if yes, determine the plan for achieving compliance

with a timeline of actions?
